JOHN FURGUSON, OF PHILLIPSBURG, PENNSYLVANIA.

LINE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 298,369, dated May 13, 1884.

Application filed January 25, 1884. (No model.) I

To all whom it may concern.-

Be it known that I, JOHN FURGUSON, of Phillipsburg, in the county of Beaver and State of Pennsylvania, have invented a new and useful Improvement in Line-Stoppers; and I do hereby declare the following to be a full. clear, and exact description thereof.

My invention relates to an improvement in line-stoppers for the purpose of'hauling on hawsers, tautening the same, and stoppering a cable or hawser while it is being taken to the capstan.

I will now describe my invention so that others skilled in the art may manufacture and use the same, reference being had to the accompanying drawings, forming part of this specification, in which,

Figurel is an elevation showing thestopper biting on a small hawser. Fig. 2 is an end View of the same, and Fig. 3 is a view showing the stopperengaged with a larger hawser.

Like letters of reference indicate like parts wherever they occur.

My improved stopper is formed in the shape or form of tongs, the two arm a b of which are pivoted near thejaws c by a rivet or bolt, d. At the outer end of the arm a is formed a yoke in which is mounted a pulley-wheel, 6. At the outer end of the arm b, which is shorter than the arm a, is a ring, f, to which ring a rope or line, g.is fastened,which passes thence through the yoke aandover the pulley-wheel 6. Each of the jaws c 0 is semicircular in form,and the axial line of the gripping-cavity is at right-angles to the line of the movement of the arms.

The operation is as follows: When it is desired to draw in a hawser, thejaws care opened so as to inclose the hawser 9. By pulling on the line gthe jaws c are closed on the hawser, and at the same timethe direction of the force being at right-angles to the line of the cavity between the jaws, the hawser is jammed therein and the stopper is prevented from slipping. When the line 9 is slacked,the jaws are easily loosened or opened, and the stopper may be removed from the hawser.

gripping devices having the gripping-cavity at right angles to the longitudinal line of the gripper have been employed in street-railways and for other purposes. I do not, therefore, desire to claim the same, as they are not capable of being applied to the purposes of my invention, first, because the clamps having the cavity on the line of the hawser are apt to slip, and can only be used on a hawser of a certain size with any degree of efficiency, and, secondly, because none of the other devices have the combination of parts employed by me which are necessary to form a safe and reliable stopper.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s

A line-stopper consisting of the arms a b, pivoted together, having jaws c c, the gripping face of each jaw being concave in form, having a sheathing of anon-metallic substance, and tbrming a cavity at right-angles with the longitudinal line of the stopper, the Wheel 6, and the line g, substantially as and for the purpose specified.

In testimony whereof Ihave hereunto set my hand this 18th day of January, A. D. 1884.

JOHN FURGUSON.
